QTextCodec subclasses must reimplement this function.
Converts the first number of characters from the input array from Unicode to the encoding of the subclass, and returns the result in a QByteArray.
state can be 0 in which case the conversion is stateless and default conversion rules should be used. If state is not 0, the codec should save the state after the conversion in state, and adjust the remainingChars and invalidChars members of the struct.

Subclasses of QTextCodec must reimplement this function.
It returns the MIBenum (see IANA character-sets encoding file for more information). It is important that each QTextCodec subclass returns the correct unique value for this function.

QTextCodec subclasses must reimplement this function.
It returns the name of the encoding supported by the subclass.
If the codec is registered as a character set in the IANA character-sets encoding file this method should return the preferred mime name for the codec if defined, otherwise its name.
